Figure Lengend Snippet: Validation of IEGs expression in Mecp2 -null mice. ( a , b ) IEGs expression in the hippocampus and prefrontal cortex of 8-weeks mice. Graphs show mean ± SEM of n = 5–6 animals per condition. Student’s t -tests were used (* p < 0.05, ** p < 0.01, *** p < 0.001). ( c ) Western Blot analysis of EGR2, c-FOS, c-Jun and NPAS4 in the hippocampus of 8-weeks mice. β-ACTIN was used as loading control. Samples from two animals per condition are shown. Graphs on the right represent quantitation of band intensity (mean values ± SEM, two tailed Mann-Whitney test, * p < 0.05, ns = not significant). ( d ) Representative immunostaining of EGR2 protein (red) in the hippocampal regions of WT or Mecp2 -KO 8-week mice, counterstained with DAPI (blue). All images were processed with ImageJ Fiji version 1.50 g. Scale bar represents 200 µm. The graph corresponds to quantitation of n = 10 images per condition (mean values ± SEM, two-tailed unpaired t test, **** p < 0.001).

Figure Lengend Snippet: IEGs gene expression response to Forskolin is dysregulated in 8-weeks Mecp2 -KO mice neurons. ( a ) Mecp2 expression in cortical and hippocampal neurons, as measured by RT-qPCR. ( b ) Schematics indicating treatment of cultured primary neurons with forskolin and time-course of sample collection. ( c , d ) Time-course of Fos , Junb , Egr2 and Npas4 transcript levels analysis for both WT and Mecp2 -KO hippocampal ( c ) or cortical ( d ) neurons upon treatment with forskolin. All expression data are relative to WT unstimulated values ( n = 3 biological replicates for each condition, means ± SEM are represented, * p < 0.05 and *** p < 0.001 in Student’s t -tests).
